Backups are permitted (and not for all media) when you legally acquired the source. Scanning a physical book is not a permitted backup, and neither is downloading a book from Anna's archive.
> Scanning a physical book is not a permitted backup
On what basis do you claim that?
You're also missing critical legal context. When a would be consumer downloads pirated media in lieu of purchasing it he damages the would be seller. When my automated web scraper inadvertently archives some pirated content on my local disk no one is financially harmed.
The question is where the boundary between those things lies.
